JOHN RALSTON, OF SLllPERY ROCK, PENNSYLVANIA.

Letters Patent 1V0. 65,432, dated Jule/2'4, 1867.

SHEEP-SHEARS.

TO ALL WI IOM IT MAY CONCERN:

Be it known that 1, JOHN RALs'roN, of Slippery Rock, in the county of Butler, and State of Pennsylvania, have invented a new and useful Improvement in Sheep-Shears; and I do hereby declare that the following is a. full, olear,and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

The drawing represents a plan or face view of my invention.

This invention relates to sheep-shears, in which a movable cutter is pivoted to the face of the stationary cutter, the latter being divided into two or more fingers or bars presenting so many cutting edges. The movable cutter is operated by the spring; and is drawn obliquely across the cutting edges of the stationary fingers, thereby producing a drawing out requiring less power and producing a cleaner out than could he done with the sheep-shears now in use.

A represents a plate which is provided with notches, whereby V-shaped fingers a a are produced which have sharp edges. The plate A is secured to one end,f, of an ordinary spring, B, the latter being of the shape generally used in sheep-shears. C is a cutter, which is pivoted by a pin, 1), to the face of the plate A, and which has one cutting edge, c. It is connected by a pin, (1, to the end 0 of the spring B, the said end 0 being slotted, as shown. By pressing the ends a and f of the spring 13 together, the cutting edge of the cutter C will be drawn over the edgcsof the finger a in an oblique direction. The slot in the end 0 of the spring prevents the latter from being too much strained. I

What I claim as new, and desire to secure by Letters Patent, is-

1. The cut-tor 0, when pivoted to the face of the cutter A and secured to the spring 13, substantially as and for the purpose herein shown and described.

2. The stationary notched bar A, when secured to the spring B, in combination with the movable cutter C, which is pivoted to the plate A and secured to the slotted end a of the spring 13, all as set forth.
